Application January 16,

4 Claims.

My invention relates to operating mechanisms for lavatory pop-up waste valves, and the objects of my invention are:

First, to provide a mechanism of this class 5 which incorporates in its handle a soap dish thus enabling both the handle for the operating mechanism and the soap dish or tray to be located in the most convenient place; namely, between the Water faucets;

Second, to provide a mechanism of this class which utilizes a turnable handle instead of a reciprocal handle or knob, thereby minimizing the efiort required to operate the pop-up waste valve;

Third, to provide a mechanism of this class which incorporates a novel means of changing the turning movement of the operating handle into a pivotal movement of the pop-up waste valve operating arm;

Fourth, to provide a mechanism of this class which may use the conventional pop-up waste valve operating arm, and packing gland therefor; and

Fifth, to provide on the whole a novelly constructed operating mechanism for lavatory popup waste valves which is durable, efficient in its action and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon which form a part of this application, in which:

Figure 1 is a fragmentary sectional view of a wash basin with my operating mechanism shown in connection therewith partly in elevation and partly in section; Fig. 2 is an elevational view of the handle member; Fig. 3 is a sectional view through 3-3 of Fig. 1 with parts and portions shown in elevation; Fig. 4 is a sectional view through 44 of Fig. 1 with parts and portions shown in elevation; Fig. 5 is a sectional view through 5-5 of Fig. l with parts and portions in elevation; and Fig. 6 is an elevational view of the lever member.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawing.

Slide member 1, link 2, lever 3, shaft 4, combined soap dish and handle 5, and collar 6 constitute the principal parts and portions of my 1932, Serial No. 587,103

novel operating mechanism for lavatory pop-up waste valves.

One type of the conventional pop-up waste valve includes a valve seat member A which is fitted in the drain outlet of a basin B. The valve seat member A is closed by a valve 0 which is provided with a stem C1 extending into the valve seat member A. The stem is supported in concentric relation therewith by guide vanes C2. The lower end of the stem C1 extends into a T fitting D and is provided with a loop portion C4. The T fitting is provided with a lateral D1 into which extends an operating arm E. The operating arm E is fulcrumed at the extremity of the lateral D1 and is enclosed by a packing gland G. The inner end of the arm E fits into the loop portion C4.

My operating mechanism includes a slide member 1 which is in the form of a pair of coaxially disposed sleeve portions 1a and lb connected by a web 10. The sleeve portion 1a is provided with a horizontally disposed loop portion 1d which is adapted to receive a hooked end 2a of a link member 2. The hook 2a forms a narrow slot 2b and the loop portion 1d is provided with a constriction 16 so that the loop and hook may be interlocked.

The upper end of the link 2 is also provided with a hook 2a which interlocks with a horizontally disposed loop 3a provided at the extremity of a lever arm 3. The loop 3a is provided with a constriction 31) similar to the constriction 16. The remaining extremity of the lever 3 is provided with a sleeve 30 adapted to fit on a vertically disposed shaft 4, and be secured thereto by a set screw 30.

The shaft also fits in a loop 1 disposed on the same side of the slide 1 as the loop Id. In order to prevent twisting of the slide member 1, lugs 1g extend from opposite sides of the sleeve portion 1b so as to engage the side of the shaft 4.

The upper end of the shaft 4 extends through a suitable bearing Bl provided in basin B and is attached to a handle 5. The handle 5 is large enough to form a soap dish. For this purpose the handle is provided with upturned marginal walls 5a having a conveniently disposed knob 51) extending outwardly therefrom. The normally forward side of the combined soap dish and handle is provided with a drain means 50.

Reciprocal movement of the shaft 4 is prevented by a collar 6.

When the handle 5 is turned in one direction, the lever 3 through the link 2 pulls upwardly on the arm E closing the valve C. Reverse moveit i ment of the handle 5 forces the link to a vertical position, thereby depressing the arm E and opening the valve C.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In an operating mechanism for lavatory pop-up waste valves, a lever connected with said waste valve and forming an oscillatable extended portion, a vertically disposed rotatable shaft, a slide mounted on said lever and including a guide portion arranged to receive said rotatable shaft, and link and lever means connecting said rotatable shaft with said slide whereby rotation of said shaft causes oscillation of said lever.

2. In an operating mechanism for lavatory pop-up waste valves, the combination with a basin wherein its drain pipe is provided with a vertically shiftable waste valve operated by a lever fulcrumed intermediate its ends by means of a fitting forming a part of said drain pipe, of a vertically disposed partially rotatable shaft, a slide mounted on said lever and including a guide portion arranged to receive said partially rotatable shaft, link and lever means connecting said partial rotatable shaft with said slide whereby rotation of said shaft causes oscillation of said lever, and a handle for said shaft.

3. In an operating mechanism for lavatory pop-up waste valves, the combination With a basin wherein its drain pipe is provided with a vertically shiftable Waste Valve operated by a lever fulcrumed intermediate its ends by means of a fitting forming a part of said drain pipe, of a rotatable shaft extending in angular offset relation with said lever, a slide mounted upon said lever, said slide including a guide slidable upon said shaft, an arm extending from said shaft, and a link pivotally connected to said slide and to said arm whereby rotation of said shaft causes oscillation of said lever.

4. In an operating mechanism for lavatory pop-up waste valves, a lever connected with said waste valve and forming an oscillatable extended portion, a partially rotatable shaft extending in angular offset relation with said lever, a slide mounted upon said lever, said slide including a guide slidable upon said shaft, an arm extending from said shaft and a link pivotally connected to said slide and to said arm whereby partial rotation of said shaft causes oscillation of said lever.
